Some people may immediately assume that Scottish and Irish are the same, but actually, they are not. They do come from the same roots, namely the Celts, but aside from that, there are some differences with their heritage, their culture, and so much more. Language is one of the most obvious differences. In the northern part of Scotland, they use the language Scottish Gaelic.
In the western portion of the Irish region, they use the language Irish Gaelic. There was a time when the Gaelic people were considered to be the lowest class of people. Those who were in the higher classes allowed them to have their own language, thinking that their language will die with them, but the language grew more as time went on.
